He had a great polo pony – why not create more just like her? So polo player Adolpho Cambiaso decided to clone his favorite horse. Lesley Stahl reports on the sport of polo, which is leading the way in cutting-edge biotechnology. Her story will be broadcast on 60 MINUTES Sunday, March 11 (8:00-9:00 PM, ET/PT) on the CBS Television Network.

Stahl went to Argentina to meet Cambiaso, whom she calls the “Tom Brady of polo.” Already ranked the best player in the world, Cambiaso is leading a new charge: in science. He’s cloning his champion horses, competing on them and winning.

Cuartetera is his best horse: a 17-year-old mare that is fast and easy to direct and can turn on a dime. She was honored last year as the best polo horse in history, and her 14 clones – named Cuartetera 1, Cuartetera 2, and so on – seem to be just as gifted.

“I think she’s born to play, you know?” he tells Stahl. “There [are] those horses in life, or like soccer players like Messi. It’s not many.”

Now, with a stable full of clones of similar temperament and skill to his champion pony, Cambiaso can swap out one Cuartetera clone for another Cuartetera clone, giving him a serious advantage on the field.
